How to enable/disable software single-stepping?

How to enable/disable software single-stepping?

[Wenbo Yang]

Hi all,

Is there any command to enable/disable software single-stepping? Or say how to 
enable/disable 's' packet while remote debugging?

My problem is:
I have a simulator integrated gdbserver which supports 's' packet. But the STUB 
doesn't. What I want is to enable 's' packet while connecting to gdbserver and 
disable it while connecting to STUB. I have tried answer "vCont;s;c" to "vCont?" 
request. It didn't work. I found the only way to enable 's' packet is don't 
register software_single_step function to gdbarch in target dependent file. 
However, that means I need two GDB binary, which I don't want.

Any ideas?

Thanks,
Wenbo

There is no way to do this, yet.
